West Allis, Wis., a corpora- .This invention relates toimprovements in window structures and more particularly to a combined sash and frame structure in which the sash is readily insertable,

into and removable from the frame by a the building to which the frame is applied.

The invention consists of a sash frame and sash having complementary slidably engaged members one of which is provided with a longitudinal channel and the other is provided with a peg engageable in the channel,

person inside the "sash'member being laterally exposed for removal from sliding engagement with the frame member ex:

cept as restrained by engagement of the peg in the chan-. I,

nel} The channeled member is further provided with a transverse channel which. opens to the inside face of the frame and through which the peg may be manipulated in the course of sash engagement with or removal from the frame. f

In the description below the invention is shown in an embodiment comprising a frame and sash combination as used in a position comparable to that of a storm sash but it will be understood that theframe and sash here described are adaptable for use as and installable in the usual position as the principal or main window installa- 1 one of the corners of the frame of a double hung'window structure embodying the invention and showing spaced parallel longitudinal channels in the jamb thereof and a transverse channel opening from one longitudinal channel to the other and fume inner face of the frame.

The invention will be described as it is exemplified in a combined storm and screen sash and frame structure which is applicable as a unit to the window opening of a build 2,740,998 Patented Apr. 10, 1956 ing having a conventional double hung sash interiorly thereof. In the particular embodiment about to be described the sash are regarded as self storing as both the glass and screen sash are intended to remain mounted in the frame year round. However, these sash must be periodically cleaned and maintained and for this purpose the structure is such that they may be readily removed from the frame from the inside of the window. Accordingly, it is unnecessary for anyone to climb the side of the building on a ladder or the like for cleaning or maintenance purposes.

As best shown in Figs. 1 and 6 a conventional window opening comprises the frame indicated generally as 10. To this frame 10 the combined storm and screen sash frame indicated generally as 11 may be mounted by means of the screws 12. The window opening is conventionally provided with double hung main sash comprising the upper sash 13 and lower sash 14 shown somewhat diagrammatically in Fig. 6.

In the present invention the combination storm and screen sash frame comprises side jambs 15, lintel 16 and sill 17. In the embodiment illustrated the frame is of the double hung type in which three sash members 20, 21

and 22 are mounted as shown in Fig. 6. Sash 20 and 21 are storm sash, and sash 2 2 is a screen sash. Each sash comprises upper and lower rails and side stiles identified as follows: In sash 20 the upper and lower rails are numbered 23 and 24 respectively and the stiles are numbered 31. In sash 22 the upper and lower rails are numbered 25 and 26 respectively and the stiles are numbered 33. In sash 21 the upper and lower rails are numbered 27 and 28 respectively and the stiles are numbered 32.

As best shown in Fig. 4 the jamb 15 of the sash frame 11 is provided with spaced parallel longitudinal channels 34 and 35 and the sash abutting surface of the jamb is divided thereby into an outer guide surface 36, an intermediate guide surface 37 and an inner guide surface 38. These guide surfaces and the channels 34 and 35'are desirably lined with a shaped metal weather strip numbered 39 in Fig. 4, the strip being provided with an inwardly turned flange 42 at the outer face of the frame and with outwardly extended flange 43 at the inner face of the frame.

The respective opposed edges of stiles 31, 32 and 33 of the sash 20, 21 and 22 are in lateral slidable engagement with the guide surfaces 36, 37 and 38' of the side jambs 15 of the frame.

37 and 38. Each sash is provided with upper and lower rail guide pegs 44 which ride in the longitudinal channels aforesaid. Stiles 32 of sash 21 are provided with linings comprising shaped metal strips 45 having outwardly turned flanges 46 at their inner faces and which are complementary in extent with the inwardly turned flanges 43 on the jambs.

Asbest shown in Figs. 3 and 7 the pegs comprise screw shanks having threaded'portions 47 engaged with thestiles but having shank portions extending beyond the edges of the stiles and into the longitudinal channels 34 and 35 in the frame jambs. vided with end kerfs 48 to receive the blade of a screw driver.

As is best shown in Fig. 7 the stiles are laterally exposed for removal from sliding engagement with the jambs except as restrained by engagement of the pegs in. the

channels.

for peg movement to and from the inside face of the Sash 20 and 22 ride on jamb surfaces 36 and 37 and sash 21 rides on jamb surfaces The pegs are'desirably pro- However, as shown in Fig. 4, each of frame' jambs 15 is provided near its junction with the sill 17 T with a lateral or transverse channel 51 whichopenslat. erally from channel 34, to 35 and thence to the inner.-' .face of the frame These-transverse channels provide frame and engagement in the" longitudinal channels as hereinafter described.

The individual sash are inserted into the frame by first engaging the top rail pegs 44 in the longitudinal channel in which it is desired topositiolr the sash; This may be done by passing the said pegs through the transverse channel 51 into registry with the desired longitudinal channel 34 or 35 and then sliding the engaged pegs upwardly in the longitudinal channel until the pegs 44 on the lower rail of the sash are in a position tobe like= wise passed through the transverse channels 51 into the same longitudinal channel. Alternatively the' top rail pegs may be first engaged in the manner shown inFig. 9' when the sash is til-ted from the horizontal toeng'agethe top rail pegs in the desired channel after which thesash isslid' upwardly and realigned horizontally to engage the lower rail pegs 44 as aforesaid. in either case the top rail pegs-act as fulcrums when the sash is pivoted to align the lower rail pegs with the transverse channel 51.

Sash is normally inserted first and may be lifted to a position above that shown in Fig. 6 and in which the top flange 52 of its upper rail 23 abuts the lintel 16of t he frame, thus providing maximum clearance for the manipulation ofsash 22 into engagement with outer longitudinal channels 34. Sash 22 may then be inserted in like manner.

It is noted that the distance between the sill 17 and lintel 16 of the frame is slightly inex'cess-of the combined dimensionof sash 20 and 22 when positioned in the frame. Accordingly when both sash are inserted in the aforedescribed manner both may then be slid downwardly in the frame to the position shown in Fig. 6 where-the lower flange 53 of the bottom rail 26 of sash 22 engages behind the shoulder 54 of sill 17. The lintel 16 is provided with a depending flange 55 which is long enough to accommodate such movement without exposing the top rail 23 of sash 20 and maintains a tight but slidable connection with the sash. In the downwardly adjusted position of the sash the pegs 44 of sash 22 will be slid below the level of the transverse channel 51 and will engage the sides of channel 34 to assist the engagement of flange 53 of rail 26 with shoulder 54 on the sill. In' this manner secure final positioning of the sash is assured and the sash must be lifted to align the lower rail'pegs44 with the transverse channel 51 as a prerequisite'to removal of the sash from the frame.

To'rem'ove sash 20and 22 from engagement with the frame, sash 20' is first lifted to engage flange 52 with the lintel thereby providingclearance space in which the sash 22 may be likewise lifted to align its lower set of pegs 44' with the transverse channel 51 to permit theswinging of the sash outwardly from the frame. During such swinging movement, the top rail pegs 44 act as axially spaced fulcrumsupon which the sash is'piv'otal. As the pegs are the'sole means for restraining inward lateral movement of the sash, alignment of the pegs 44 with the transverse channel 51 readily permits such movement. It'is noted that flanges 42 'on the jamb linings 39 slidably engage the outer faces ofthe sash stiles 31 and 33. Accordingly, these flanges assist the pegs 44 in'r'estraining outward lateral movement of the sash.

channels 35 by first engaging its upp'erfra'il pegs 44 with the longitudinal channel and then pivoting the sash on the engaged pegs to pass its lower rail pegs 44 through the transverse channel 51 and into alignment'wi'th the In the lowermost position oftsash 21 the flange 56 ofits" lower rail 28 seats behind shoulder 57 on sill I7 and the" lowermost pegs 44 are out of registry with the transverse channel '51 and engaged below thetransverse channel and in the longitudinal channel 35. The lower rail of both storm and screen sash are fragmentarily shown in Fig. 4 in the closed position of the sash.

The upper rail 27 of sash 21 is desirably prov'ded with weather stripping 60 which engages the inner face of lower rail 24 of sash 20 in the closed position of the sash.

As best shown in Figs. 5, 7 and 8, the illustrated sash stiles are shown with medial longitudinal channels 61. These are a matter of choice, however.

Asbest shown in Figs. 2, 4 and 8 the portion-ofthe frame below the sill 17 is provided with a sill board 62 adjustable in the frame. This board may be cut to size in order to properly fit the combination storm and screen sash to the window opening. This structure, however, constitutes no part of the present invention and will not be further described. Each sash 20, 21 and 22 is desirably provided with handles 63, 64 and 65 respectively, to facilitate manipulation of the sash in the frame. Handles 63 and 65 are mounted to swing out of the plane of the inner face of the sash so as not to interfere with sliding movement of sash 21. Handle 64, however, may be mountedwherever convenient, and preferably on the inner face of sash rail 28.

I claim:

1. In a window structure a sash frame comprising a lintel, sill and side jambs, each jamb being provided with paired laterally spaced channel ways, a first transverse way laterally connecting said paired ways and a second transverse way leading from one of said ways to an exposed face of the frame, a pair of sash havingtop and bottom rails and side stiles slidable on said jambs and having pegs projecting oppositely beyond said stiles and engaged in the respective ways for laterally confining said sash in said frame, one of said sash being provided with stop flanges on each stile and projecting outwardly therefrom in the general plane of the sash to an extent greater than the distance between frame jambs, said stop flanges comprising means engaging said exposed face of the sash frame to limit movement of the pegson said sash through said second transverse way to a position in which said pegs are aligned with said one way.

2. The device of claim 1 in which the distance between the frame lintel and sill is in excess of the inter-rail distance of two sash received in the same jamb way whereby to permit at least limited movement of such sash in said frame, said first and second transverse ways being aligned and spaced from said sill a greater distance than the spacing of the'sash pegs from the edge margin of the bottom sash rail whereby said pegs may be selectively shifted between positions of alignment and non-alignment with said aligned transverse ways dependent on the position ofth'e' sash in the frame;
